- POT FOR GLASS-MELTING FURNACES.

I Application filed June 24, 1926, Serial No. 118,256, and in Germany June 25, 1925.

For a more efiicient use of the heating plete profit from the heating-gases is not.

It) ensured in spite of the increased bottomsurface;

Now, according to the present invention a complete use of the heating or fire-gases touching the bottom of the pot is obtained or ensured by arranging open grooves or passages on the under surface of the bottom of the pot, said grooves or passages running parallel with each other or crosswise from edge to the opposite ed e in such a manner that the heating or re-gases are drawn through said open rooves or passages and the heat is supplied to the ,bottom of the pot in permanently fresh quantities.

The object of in the drawin in two forms 0 construction.

Fig. 1 represents 'in a vertical section and Fig; 2 in a view from the bottom the first 30. form of construction.

Fig. 3 represents in aview from the bottom the second'form of construction in which the grooves or passages arranged in the bottom run crosswise.

As shown in Figs. 1- and2, open grooves or passages 5 arranged in the bottom a of tlie melting-pot run from edge to the opposite edge of the pot in such a manner that the invention-is represented annexed to the description.

the bottom-surface is increased on the one hand and a better passage of the tire-gases 0 on the bottom is ensured, on the other hand,

so that the heat is supplied to the bottom in permanently fresh quantities within .the grooves or passages.

In the form of construction represented by Fig. 3 the grooves or passages 7) are arranged crosswise, so that the underside of the bottom is provided with downwardly projecting parts 0. This form of construction has the advantage thata better passage of the fire-gases at the bottom a or within the passages 12 is ensured in any suitable position of the pot containing molten glass.

What I claim is:

1.,Pot for glass-melting furnaces which consists in that the underside of the bottom is arranged with open grooves or passages running adjacent one another from one edge to the opposite edge of the pot.

2. Pot for glass-melting furnacohvhich consists in that the underside of the bottom is arranged with open grooves or'passagcs running )arallelfrom edge to the opposite edge of tie pot.

3. Pot for glass-melting furnaces which consists in that the underside of the bottom .is arranged with two series of open grooves
